- W3134995896 abstract "Abstract The operation and maintenance of traditional substations is not timely due to the huge cost of manpower and material resources. In the context of ubiquitous power Internet of Things, the operation and maintenance of substations uses a large number of sensor equipment. However, the traditional rs485 bus is difficult to transmit large-capacity data such as waveform curves and images in real time, and the optical fiber transmission form of industrial Ethernet will bring higher costs, which will hinder real-time monitoring. This project intends to achieve impedance matching by adjusting the resistance of the pull-up and pull-down resistors and terminal resistors, thereby increasing the communication rate of the rs485 bus. To this end, we specially designed a simple STM32 single-chip microcomputer to match the realization of the project. The hardware part of this design adopts the STM32F103RCT6 single-chip microcomputer as the main control chip, using MAX3485 as the serial port chip, and at the same time choosing the resistance and capacitance of 0805 package, using AMS1117 Packaged voltage regulator chip." @default.
